THE NUMBERS, EXPLAINED
How to use this calculator.
Stack-bond rectangular texture only, with aligned vertical joints. Module sizes include mortar; guides beyond the edge are trimmed.
Start with your inputs
Enter texture surface width (mm), texture surface height (mm), brick module width including mortar (mm), brick course height including mortar (mm). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Texture surface width (mm) | 100 |
| Texture surface height (mm) | 50 |
| Brick module width including mortar (mm) | 20 |
| Brick course height including mortar (mm) | 10 |
A worked example
With the example inputs above, brick columns (count) is 5. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Brick columns (count) | 5 |
| Brick courses (count) | 5 |
| Final column width (mm) | 20 |
| Final course height (mm) | 10 |
How this is calculated
Brick columns (count)
Round surface width divided by module width upward.
Brick courses (count)
Round surface height divided by course height upward.
Final column width (mm)
Subtract full earlier modules from surface width.
Final course height (mm)
Subtract full earlier courses from surface height.
Symbols and units
- a
- Texture surface width (mm)
- b
- Texture surface height (mm)
- c
- Brick module width including mortar (mm)
- d
- Brick course height including mortar (mm)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Stack-bond rectangular texture only, with aligned vertical joints. Module sizes include mortar; guides beyond the edge are trimmed.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Brick columns (count); Brick courses (count); Final column width (mm); Final course height (mm). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Stack-bond rectangular texture only, with aligned vertical joints. Module sizes include mortar; guides beyond the edge are trimmed.
